- Notes:
-
- [C1] - Means code used for Cellular One service
- [1] - for cellular in Pittsburgh, PA A/C 412 in some areas
- [2] - indicates that you are not local and maybe how to reach you
- [3] - found in Pac Bell territory; Intercom ring causes a distinctive
- ring to be generated on the current line; Hold keeps a call
- connected until another extension is picked up
- [4] - applied once before each call
- [5] - A.C.R. blocks calls from those who blocked Caller ID
- (used in C&P territory, for instance)
- [6] - cancels further return attempts
- [M: *xx] - alternate code used for MLVP (multi-line variety package)
- by Bellcore. It goes by different names in different RBOCs.
- In Bellsouth it is called Prestige. It is an arrangement of
- ESSEX like features for single or small multiple line groups.
-
- The reason for different codes for some features in MLVP is that
- call-pickup is *8 in MLVP so all *8x codes are reaasigned *5x
